Editor’s Note

OpenAI officially released the GPT-5.6 family, with flagship Sol topping Terminal-Bench 2.1 — initially only open to trusted partners; Nvidia shipped Cosmos 3, the world’s first fully open-source world model, pushing embodied intelligence. On the paper side: self-evolving multimodal agents (ManimAgent), CRAFT counterfactual credit assignment, tapered language models, and a learned video coding standard (MLVC, ECCV 2026).
